Cons

The BlueAnt Z9i is the improved version of the well received Z9. It has all the functions of the Z9 with some added features and accessories. It will pair with 5 devices at the same time and can be connected to 2 simultaniously. Another nice feature is it's firmware upgradability. Overall it has great comfort due to it's light wheight and the possibility to change earbud sizes. The sound is clear and the connection strength is nothing short of stellar for a device of this kind. Its two microfones combined with BlueAnt's noise cancelling technology make for a very solid reception for anyone talking to you.
